In the views of the drawing ll) represents a container'wall having.:arhole H in which my dispensing device is mounted. As seen in Figures 1,2 and 3 the inner prleft-hand end. of the device extends into the container, that is, extends to the left or the container wall l0. My-device has an outer cylinder or sleeve I 2 oflongitudinal form. The cylinder t2 has threads 22 formed thereonat alts left hand end. -An inner nut 20 threaded 5011 the threads H offcylinder I2 is positioned on the ains'ide of the container and secures the cylinder :12 against longitudinal movement in one direction. outer nut 21 threaded on the thread 22 of-the cylinder 12 is;positioned=on the outside of the container and secures the cylinder |:2 against longitudinal movement in theother direction. .Suitablegaskets or seals areprovided between the nuts 20 and 21, respectively, and the wall H) to .;-prevent leakage through the hole H around the cylinder I2 as-illustrated'in Figure 3.

An inner cylinder 'orrreceptacle l3 somewhat longer than the cylinder 12 'slida'bly fits within the cylinder "l2. Theinnercylinder 13 is adapted to reciprocate. tothe right and left in the outer cylinder l2. To providefor adjustment of the internal capacity of the inner cylinder [3 a threaded cap or stopper 1-4 is threadably secured to theen'd within-the rcontainer; Bymoving the stopper 'M the measuring capacity of the receptacle 1T3may-be si1itabIy varied.

Near the inner or left-hand end of the internal receptacle 1'3 .there "are provided two inlet openings 15; These inlet openings i5 are providedito ipermit liquid :to freely and quickly flow into the receptacle l=3 when the receptacle 1 3 is moved inwardly or to the left :in the position shown in Figures 1 :=and-3. When in this position liquid within the container having the container wall 10 flows through the inlet openings 15 to fill the receptacle 13; ,-The inlet openings liare so positioned that when the receptacle l3 A small hole or air vent I! is provided in the upper wall of the receptacle I3 immediately above the outlet opening I6. When the receptacle I3 is in its retracted position shown in Figures 1 and 3, the outlet opening I6 and air vent I] are closed off by the inner walls of the outer cylinder I2 .cylinder- I2.

and no liquid may flow outwardly from'the re- 1 ceptacle. Upon movement of the receptacle I3 to its extended position shown in Figure 2 the outlet opening I6 is uncovered and liquid within the receptacle may freely fall and flow from the receptacle. In this extended position the air vent I1 is also uncovered to permit air to enter the receptacle as liquid flows from it. Upon movement of the receptacle I3 to a position intermediate of the two illustrated retracted and extended positions, the outlet opening I6 may be partially closed oil and the flow of liquid therefrom may be restricted and the amount flowing therefrom in a given period of time is determined by its viscosity in 'relationship to the affective or uncovered portion of the outlet opening I6.

The receptacle I3 is formed of a cylinder having the stopper I4 positioned at its inner end. At the outer or right-hand end of the receptacle I3 the end wall is formed by an inner end cup 3I pressed into place as shown in Figure 3. An

outer end cup 32 is positioned adjacent the cup.

3I and extends out over the edge of the cylinder I3. A' suitable sealing material 34 is positioned around the circular edge of the cylinder I3 between the cups 3I and 32. The inner cup 3I, the outer cup 32 and thesealing material 34 form the outer end wall of the receptacle I3. The outer end cup 32 extends radially outward from the cylinder forming the receptacle I3 and is then formed to extend back parallel to the axis of the receptacle I3 to form the flange 33. The annular flange 33 accommodates acircular gasket 35 of rubber or other suitable substance adapted to form a seal. 1

The outer or right-hand end of the outer cylinder I2 has a flange formed thereon. This flange is denoted by the reference character 36. The gasket 35 tightly engages the circular flange 36 and the end face of flange 36 forms a valve seat engaged by the gasket 35. An end bar or traverse. piece 28 is secured to the end of the reciprocal receptacle I3 by means of the bolt 38. The bolt 38 has a square or other non-circular end portion 39 which complementarily fits into a square or similar noncircular recess in thecup end 3|. The bolt 38 extends out through an opening in the end wall 32. A square or other non-circular opening is provided in the cross piece 28 and there is a square or non-circular portion 40 of the bolt 38 which fits into such openings. A knurled nut 31 threadably engages the bolt 38 and secures the cross piece 28 to the end of the receptacle I3. By reason of the non-circular form of the portions 39 and 40, the bolt 38 is prevented .from

rotating and the cross piece 28 is prevented from turning on the bolt 38. The cross piece 28 has ear portions 29 formed at its ends and disposed at substantially right angles to the main body of the cross piece 28. By the arrangement shown, the cross piece 28 and the ears 29 are made a part of the movable receptacle I3 and so move longitudinally of the cylinder I2 as the receptacle I3 is reciprocated.

To provide for the reciprocal movement of the inner cylinder or receptacle I3 a set of levers is provided. This set of levers is comprised of a pair of first levers 23 arranged parallel to each other on opposite sides of the cylinder I2 and another pair of second levers 24 also arranged parallel to each other on opposite sides of the The left-hand end of the second levers 24 are pivotally secured to the first levers 23 at a point intermediate the ends of the levers 23 by means of the pivot pins 26. The handle 25 extends across between the outer or right hand ends of the levers 23.

The right-hand or lower ends of levers 24 are pivotally secured to the ears 29 of the cross piece 28 by means of the pivot pins 30. Movement of the levers 24 by movement of the levers 23 causes the cross piece 28 to reciprocate the receptacle I3 in the cylinder I2.

At the lower or left-hand end of the levers 23 hub or cup portions 2! are formed integral with the levers 23. The center of the hub or cup portions 27 is the pivot upon which the levers 23 swing as the handle 25 is raised or lowered. Circular openings are centrally located in hubs 21.

An adjustable and selectively positioned mounting is provided in my device for the hub or cup portions 21 whereby the pivot points upon which the levers 23 swing may be changed in location along the length of the cylinder I2.

The mounting for the levers of my device, particularly the pair of levers 23, comprise the pair of yoke members denoted generally by the reference character 42, the coil springs 46, the tension members 49 and the threaded bolts 53. These members are shown in spaced relationship in Figure 6. The yoke members 42 each have an arcuate portion 43 and end portions 44 at its opposite ends. The arcuate portion 43 is adapted to complement the outside cylindrical surface of, and to engage, the cylinder I2. The end portions 44 extend radially outward from the cylinder I2 and on opposite sides of the cylinder I2. The end portions 44 on each side of the cylinder I2 are spaced from, and disposed parallel to, the end portion 44 of the other yoke member 42. The spaced and parallel relationship is well shown in Figure 6. cross section so that each pair of end portions 44 on the opposite sides of the cylinder I2 together form the major portion of a hollow cylinder but with a slit or gap between the two adjacent end portions 44; The inner surface of-each pair of end portions are provided with threads 45. The threads 45 of each pair of end portions 44 are adapted to threadably engage the threaded portion of the bolts 53. In other words, the mated pairs of end portions 44 provide threaded receptacles for receiving the male threads of the two bolts 53.

The pair of tension members 49 of hollow cylindrical form surround and embrace each pair of end portions 44. The inner opening of the tension members 49 accommodates thetwo end portions :44 insertedtherein. To permit the The end portions 44 have an arcuate tension zmembers :49 ,=t0 accommodate. themselves to "the :outer; cylindrical.rsnrfacev of the cylinder I2 and. to providea good .rengagement. between the tension members 49 andlthecylinder I2, there are two .arcuate recesses .:50.formed on :the. inner end of .each tension .member 49.. The recesses 50,;are shapedv to complement, the outer. surface of. the cylinder .|.2-.and such that the @tension members .49 may :tightly ,engage the cylinder 12. To permit the tension members .49 to .fitaround the arcuate portions 43. of the'yoke members, re.- c'e'sses. 5| are iprovi'ded .in the .ends. of the tension membersi49. The'recesses 5| onopposite sides of the tension members..:4.9accommodate the arcuateportions :43 extending from, and .connecting, -:the .end: portions .44. These arecesses :5I

Atrthe-other and .larger end of thecoil spring 46 there is provided a. hooked end portion 4'|. The .hookedpo'rtion 4"! is for the purpose of anchoring thisother or larger end to-the levers 23. The hub or cup portion :2Izof the levers 23 have provided. therein three \equi-distantly positioned small openings 4|. The hooked portion 41 of each. spring 45 fits within a selected one of the three openings 4|. The tension on thespring 461s adjusted by determining which of the openings 4| the hooked portion 41 .is to be engagedin upon assembling of the parts. Figures 1, 2 and 3 show, the hooked .portion 41 extending out through one of theopenings 4| of'the hub or cup portion 21. As the hub or 'cup'por'tion 21 revolves with the swingingoftheilevers '23 the position of i the hooked .portion changes.

Itais to be notedzthat the-non-circular portions tsland Mi of bolt 38 and. their..,nonrotative engagement iincup. 3| and the traverse piece 28, prevent-the receptacle I3 zfrom, rotating relative 'to the. levers. 2,3;and124. Thus theoutlet opening is alwaysmaintainedin a d Wn position to. permit :liquid :to :fiow therethrough when the dispenser. is iin'gits extended position.

To -mount thedispenser ,in the hole II of the container wall .IIi the cylinder I2 with the receptacle L3 therein and having the outside nut 2| mounted thereon butwith the :inside nut 29 removedtherefrom is.:inserted:into the hole II from outside the container. Theinside nut 20 is thenscrewed onto thecylinder I2 to the position shown in :t-hedrawing. The inside nut 2| is then tightened 11p, :against the .container wall to compressltheggasketnor packing adjacent the container wall and to tightly hold the cylinder I 2;in to the position shown inthe, drawing.

The mounting for the hub 21;,of levers 23 is then positioned on the cylinder -|2--by placing the yoke members 4fi'aroundtheecylinder I2 to embracethe same. Theend members 44 of the yoke members are positioned to.extend radially out in a horizontal planeon opposite sides ofthe cylinder I2. The coil springs dfitand tension members .49 are then moved iradially inward to surround the respective pairs ofend portions on the opposite sides of the cylinder .12. In nesting the respective pairs .of ends .44, the springs 48 and tensionmembers 49 the end-portions 48 of the spring are positioned in. agroove 52 and between the gap or slit between the spaced end portions 44. After the springs 46 and tension members 49 are nested with, .and positioned around, the pairs of end portions 44 the bolts 53 are moved radially inward of .the cylinder I2 so that the threadedportion of the bolts 53 protrude into the central opening of the tension members 49 andengage in the threaded portion 45 of the end portions 44. Thebolts '53 are turned. in- Ward to threadably engage the thread 45 in the end portions 44. The head of each bolt.53 engages the outer annular edge of a respective tension member 49. As the'bolt 53 is turned inwardly by a screwdriver the head of the bolt presses upon the tension member 49 and forces it inwardly against the cylinder I2 to tightly engage the outer wall-of thecylinder I2. As the tension member 49 is pressed inwardly towards the cylinder !2 the end portions 44 threadably engaging thethreads of :thebolt 53 are pulled radially outward from the cylinder I2 to cause the arcuate portions 43 of the yoke membersto flex and tightly engage the cylinder I2 at the top and bottom thereof. There is thus a tight engagement of the yoke members '42 with the cylinder I2, on itsupper and lower cylindrical surface. The yoke membersare preferablynmadeof a resilient metal such as steel which will permit the :yoke members to resiliently flex when the bolts 53 are turned inwardly and whlchpermits the yoke members to resume their normal arcuate shape when the tension is removed upon the turning of the bolts 53 radially outward. The tension members 49 embracing the end portions 44 also tightly engage the outer cylindrical surface of the cylinder I2 upon the turning inward of the bolts 53 and thus further anchor the yoke members and the mountings carried on their opposite ends to the cylinder l2.

Before the bolts 53 are tightened down to cause firm engagement of the yoke members and tension members with the walls of the cylinder I2 the position of the yoke members and mountings carried thereon is selected by moving the yoke members longitudinally of the cylinder I2 to the desired position. As seen in the drawing there is considerable latitude in the choice of positions where the mountings for the levers 23 may be positioned. While the yoke members and the springs, tension members and bolts carried thereon loosely engage the cylinder I2, they may be slid longitudinally of the cylinder I2 to a desired position such as that shown for example in the views of the drawing. When in the desired location the screw bolts 53 are turned inwardly to cause the tension members to press firmly against the outer surface of the cylinder I2 and to cause the yoke members to resiliently flex and tightly grip the cylinder I2. The mounting provided by the yoke members, springs, tension members and bolts is thus tightly secured to the cylinders I2 and resist further longitudinal movement.

After the mountings are secured in the desired position with the end portion, coil springs, tension members, and threaded bolts disposed horizontally, the levers 23 and are mounted in position. The levers 23 and 24 being made of metal are adapted to flex somewhat so that the hub or cup portions 21 may be resiliently spread apart to permit the hubs 2'! to slide over the bolts 53 and down into the position shown in the views of the drawing. With the levers 23 in raised position, the hooked portion 4'! of the springs is inserted into one of the small holes 4| in the hub 21. The hooked portion 51 holds the hub portion 21 radially inward toward the cylinder I2 to secure it in the position shown in the drawing and also provides that the levers are resiliently biased in their swinging motion upon the pivot provided by the adjustable mounting described. As the levers 23 are moved downwardly by the handle 25 the springs 46 engaging the cup or hub 21 resiliently resist the downward movement and upon release of the handle 25 the springs 48, acting through the hooked portions 41 on the hub 27 resiliently bias the levers 23 to their upward position illustrated in Figure l. r

The lower extremities of the levers 24 riveted by pivot pins 30 to ears 29 of the transverse piece 28 are secured to the outer end of the receptacle I3 by placing the transverse piece 28 in engagement with the bolt 38 to the position shown in the drawing. l'he knurled nut 3? is then screwed down at the cross piece 28 to which the levers 24 are pivotally attached and the levers are thus secured to the receptacle I3. The levers may be easily detached from the receptacle by the removal of the knurled nut 31 and the pulling of the transverse piece 28 off the bolt 38. With the levers disengaged from the receptacle I3 the receptacle may easily be withdrawn from the cylinder I2 for cleaning or repair.

From the views of thedrawing it is seen that when the handle 25 is in the upper position, shown in Figure 1, the force of the coil spring causes the levers to retract and move the receptacle I3 into its retracted position of Figure 1. Upon manual movement of the handle 25 downwardly to the position of Figure 2 the action of the levers is such that the receptacle I3 is moved to its extended position to uncover the outlet opening I6 as shown in Figure 2. The degree of the extension of the receptacle I3 out from the cylinder I2 is determined by the length of the levers and by the position of the pivot upon which the levers 23 swing. By moving the mountings for the levers 23 longitudinally of the cylinder I2 the stroke of the levers is adjusted. For universal use of the dispenser it is desirable to have the pivot mounting for the levers 23 adjustable so as to be located as desired along the length of the cylinder I2. Sometimes it is desired to use the device to dispense liquid in measured quantities in which case the receptacle is held in its extended position until its contents have drained off. When thus used it is desired that the outlet opening I6 be entirely uncovered to provide for quick withdrawal of the contents of the receptacle. For this purpose the dispenser would be held in the position of Figure 2 until the contents of the receptacle I3 had flowed therefrom and it would be known that the amount which flowed out would be the full contents of the receptacle as determined by the adjustment of the stopper I i. Sometimes it is desired to use the device as a valve to dispense a smaller quantity of liquid, the quantity then being determined by the time that the handle 25 is held down, the effective uncovered portion of outlet opening I6 and the viscosity of the liquid. For so dispensing quick shots of quantities smaller than the total capacity of the receptacle it may be desired to have the outlet opening I6 only partially uncovered in each reciprocating stroke of the receptacle. To provide only a partial uncovering of the outlet opening I6 when the handle 25 is pushed to its downward position, the location of the pivot mounting for levers 23 may be adjustively determined by moving the mounting longitudinally of the cylinder I2 and securing it in the desired position as described. By a quick manual stroke or flip of the handle 25 a small shot of liquid, less than the capacity of the receptacle, may be dispensed, the size of the shot being determined by the viscosity of the liquid and the time during which the handle 25 is held in a downward position, this being quickly ascertainable from experience.

' The disclosed device is flexible in operation, is quickly adjustable and efiiciently meets the needs for universal use of such dispensers.

Although I have described my invention in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
